Glaucoma and capillary perfusion

Elevated IOP is important but not the sole factor responsible for retinal ganglion cell (RGC) death and optic nerve damage in glaucoma. There is increasing evidence that visual loss correlates with macular inner retinal thinning. A total of 148 eyes...

Investigating the effect of signal strength on mean retinal nerve fibre layer

The aim of this study was to determine the effect of signal strength on mean retinal nerve fibre layer (RNFL) using spectralis optical coherence tomography (S-OCT). Thirty normal subjects were imaged with S-OCT using variably dense Bangerter foils to alter...

Relating metamorphopsia severity and OCT findings in advanced epiretinal membranes

The authors present the findings of a retrospective study to correlate metamorphopsia and ectopic inner foveal layers (EIFL) or ‘central bouquet’ abnormality (CBA) in patients with advanced stages of epiretinal membrane (ERM) following the new OCT‐based grading scheme as described...

Imaging papilloedema vs. pseudo-papilloedema

Quite often, in the working week as an ophthalmic photographer, you will be given that patient with ‘swollen discs’ to image. These swollen discs could be a number of things, but mainly fall into one of two categories: papilloedema or...

Image Analysis and Modelling in Ophthalmology

Recent advances have revolutionised ophthalmic imaging and helped understand the pathophysiology of ocular diseases and thus help in the diagnosis and management of ocular diseases. The authors of this book have gone through most of the available imaging techniques available...

Screening for Sickle Cell Retinopathy (SCR): Why we do wide-field imaging, OCT/OCT-A for SCR – Newcastle upon Tyne Hospitals NHS Foundation Trust

I have been working in ophthalmology for over five years as a photographer and research co-ordinator, and it is fascinating, rewarding, and interesting to learn all about the different diseases associated with the eye. One condition that has been a...

Handbook of Retinal OCT (Second Edition)

Duker et al. present the second edition of their Handbook of Retinal OCT. It’s an upgrade from their last edition in many respects – there’s an enhanced digital version, the pages have a nice glossy sheen which makes it feel...

Comparison between findings in OCTA and FA in patients with diabetic retinopathy

In this study the authors present a prospective cross-sectional comparative study of typical findings of diabetic retinopathy to analyse the agreement between the image modalities of optical coherence tomography angiography (OCTA) and fluorescein angiography (FA). Fifty-three eyes of 42 patients...

Smartphone ophthalmoscopy vs. slit-lamp biomicroscopy in diabetic retinopathy

In this prospective, comparative, clinical study the authors’ aim was to assess the reliability and accuracy of smartphone ophthalmoscopy as compared with standard slit-lamp biomicroscopy in the grading of diabetic retinopathy. One hundred and twenty consecutive, new, diabetic patients underwent...

Assessment and management of dry eye disease

This paper is an update on the assessment and management of dry eye disease (DED). According to the second International Dry Eye Workshop 2017, “Dry eye is a multifactorial disease of the ocular surface characterised by a loss of homoeostasis...

Adaptive optics imaging: resolving single cells in the living eye

The human retina is unique in the central nervous system (CNS) in that it can be directly visualised non-invasively. Technological advances of several imaging modalities, including optical coherence tomography (OCT), multichannel scanning laser ophthalmoscopy (SLO) and fundus photography, have afforded...

Atlas of Clinical and Surgical Orbital Anatomy (Third Edition)

This textbook highlights in its preface to the third edition that considerable research has been undertaken in the fields of orbital and periorbital anatomy since 1994 (first edition) and 2011 (second edition). Various topics have been elucidated, such as the...
